gene-altered 中文意思是什麼
-
In this study, the avermectin - producing strain streptomyces avermitilis was studied and the avermectin biosynthesis gene cluster in the genomic dna of streptomyces avermitilis s - 2 was altered by the method of gene engineering. insertion inactivation of aved gene in the cluster by introducing apramycin resistance gene into aved gene resulted in the disappearance of " a " components of avermectins. when avec gene was inactivated by the same way, four " 1 " components were lost and only " 2 " components, the potential precursor of ivermectin, were accumulated
將該基因簇中的aved基因通過插入外源的安普黴素抗性基因片段使其失活，導致發酵產物中4個a組分（不需要的組分）的消失；將基因簇中的avec基因通過同樣手段，使其失活，導致發酵產物中4個「 1 」組分的消失，而主要積累「 2 」組分（進一步改造可成為伊維菌素的前體b _ 2組分） 。 -
